Target future OP airdops to people who got rekt on L1 gas fees and have migrated to optimism with consistent activity. That is the crux of it. These people have often spent in excess of 1-100+ eth during times of high network costs. They were and are the backbone of the Mainnet and should have been targeted in OP #1. Also this is a perfect way to onboard more heavy users of L1 and entice them to drive volume in our ecosystem.
Feel free to add any suggestins.
